Mark 1:2-5
1:2 As it is written in Isaiah the prophet,
“Look, I am sending my messenger ahead of you,
who will prepare your way,
1:3 the voice of one shouting in the wilderness,
‘Prepare the way for the Lord,
make his paths straight.’”
1:4 In the wilderness John the baptizer began preaching a baptism of repentance for the forgiveness of sins.
1:5 People from the whole Judean countryside and all of Jerusalem were going out to him, and he was baptizing them in the Jordan River as they confessed their sins.
